Supposedly pic related is one of the most dangerous lab chemicals. It's not the cold that kills, it's the displacement of air and the fact that humans can't smell it that are problems.

that delicious little shit, apart from being highly corrosive, if it enters the human body (and it can pass through the skin due to its small size) it complexes with the Ca++ and Mg++ ions (which are litterally everywhere), which can cause, amongst others total destruciton of the affected nervous system, and a high risk of cardiac arrest.
And for the fun finale, you cant use glass glassware, it can filter through it by capillary action. So you have to get quartz glassware

>>9004388
The best part is that exposure takes around 4 hours to show any symptoms, and starts with intense pain.

>>9004405
and good luck finding an hospital that can treat that shit

I use this shit every week at work its one of the active ingredients in aluminium cleaner

Yes, that's ng/kg, as in nanograms per kilograms.

https://en.wikipedia.org/wiki/MPTP

>MPTP itself has no psychoactive effects
>MPTP is a prodrug to the neurotoxin MPP+, which causes permanent symptoms of Parkinson's disease (by destroying 50-70% of dopamine neurons in a certain part of the brain)

>The neurotoxicity of MPTP was hinted at in 1976 after Barry Kidston, a 23-year-old chemistry graduate student in Maryland, US, synthesized MPPP with MPTP as a major impurity, and self-injected the result. Within three days he began exhibiting symptoms of Parkinson's disease.
(MPP+) is toxic and acts by interfering with oxidative phosphorylation in mitochondria by inhibiting complex I, leading to the depletion of ATP and cell death.[1] It also inhibits the synthesis of catecholamines, reduces levels of dopamine and cardiac norepinephrine, and inactivates tyrosine hydroxylase.[1]
>Complex I is the largest and most complicated enzyme of the electron transport chain.[6]

Sodium Pentothal

>Dimethylmercury

>Dimethylmercury is extremely toxic and dangerous to handle. Absorption of doses as low as 0.1 mL can result in severe mercury poisoning.[3] The risks are enhanced because of the high vapor pressure of the liquid.[3]

>Permeation tests showed that several types of disposable latex or polyvinyl chloride gloves (typically, about 0.1 mm thick), commonly used in most laboratories and clinical settings, had high and maximal rates of permeation by dimethylmercury within 15 seconds.[8] The American Occupational Safety and Health Administration advises handling dimethylmercury with highly resistant laminated gloves with an additional pair of abrasion-resistant gloves worn over the laminate pair, and also recommends using a face shield and working in a fume hood.[3][9]

>Dimethylmercury crosses the blood–brain barrier easily, probably owing to formation of a complex with cysteine.[10] It is eliminated from the organism slowly, and therefore has a tendency to bioaccumulate. The symptoms of poisoning may be delayed by months, resulting in many cases in which a diagnosis was ultimately discovered, but only at the point in which it is often too late for an effective treatment regimen to be successful.

reminds me of a youtube video, I cant find it but it was like this:

>idiots pour liquid nitrogen into a swimming pool
>"haha whoah look at this cool fog"
>nitrogen gas expands as it evaporates, displacing all the oxygen in the area
>idiots just start falling over from lack of breathing

Well as the saying goes Chemists, they change the way you live and die!
Here are some fun poisons:
https://en.wikipedia.org/wiki/Saxitoxin
https://en.wikipedia.org/wiki/VX_(nerve_agent)

What disturbs me more is that we've taught computers how to invent new nerve agents! The same techniques used to develop drugs have been used to develop pesticides! A simple change of the target structure could be used design new nerve agents for people rather than insects! With quantum superiority around the corner and the huge size of chemical space, we could invent agent every week or so!

So I've hear most people die when they go to help someone else who passed out. They reach down to pick them up and WHAM! lungs full of nitrogen insta-asphyxiation DOUBLE KILL!

I've used this stuff in pickling paste and i was burned by it. Make sure you have a tube of calcium gluconate paste nearby. I had to go to A+E it was painful; i was told that the paste contained nitric acid so that you could tell if you had been burned because HF kills the nerve endings before the impulse can reach the brain. I'm sure that's not true but it made me worry. I also dropped some on the factory floor and it took off the two-pack paint off the floor.

not memeing don't get tricked by Hollywood like normies do and think this shit is benign. I've only smoked maybe 10 times and shit turned me from top of class at university to having to work 18 hours a day during intensive periods to maintain my grade average. Literally smoking once WILL fuck with memory/attention span permanently even if it's only a little

>>9007194
In truth alcohol is probably more dangerous in terms of people killed because of people getting alcohol poisoning, doing stupid shit while drunk, drunk driving etc.

Technically dihydrogen monoxide is really dangerous by this metric too. You are more likely to die by really common chemicals than the rare ones posted above

congratulations on being incapable of distinguising real advice from bait. Cannabis ruined me. there haven't been many studies but only the most assholish of weed smokers will deny that short term memory loss even after stopping is by far the most prominent negative side effect of THC.

>>9007387
I'm assuming people here are smart enough to make decisions about whether they want to live or not. My uncle drank himself to death over years. It's a decision based on mental health or having a shit life.

People here should be more concerned about brain health though. Cannabis is the worst drug for causing brain deterioration, alcohol's probably second worst besides getting hit over the head.

>>9007194
You smoked marihuana when freshman.
Don't blame weed. You are just a brainlet.

>>9007446
yeah because everyone conveniently starts smoking when they're 25. I didn't smoke till I was 21 which is a decade later than a lot of weed smokers. What age were you?

Also yes weed fucks with brain development but I'm talking about mild brain damage

The alcohol didn't kill. Colliding with a light pole at 70 mph was the cause of death.

This is why cannabis is an insidious drug. The first thing it does is attack your logic centers so shit like this makes sense.

Interested anons should look up cubic gauche nitrogen. It's an all-nitrogen network solid with the highest chemical energy density known or theorized. Even better, it's metastable and mechanically stable, so it would presumably make an outstanding explosive lens material.
